Rubber Sheet Check It Out And Buy It

First, look at the appearance of rubber sheet quality. First look at the color, color rubber plate color golden yellow, whole body translucent, carbonized rubber plate is bronze or brown, color uniform and glossy. With moderate hardness, acid and alkali properties. Can be in the temperature of -30 ~ +60 º 20% between the acid (alkali) liquid work. Uses: can be used for punching a variety of acid and alkali requirements of the better sealing performance of the gasket.

  Second, check the quality of rubber sheet paint. The floor placed in the light benefits to see whether the surface of the bubble, pitting, orange peel phenomenon, look at the paint is rich, full, smooth. For example, the surface of the plate in the purple, for high pressure plate for sale. Therefore, the purchase in addition to check the appearance of quality, the main determination of a tensile strength can be. In the transverse direction of the plate, intercept 200mm × 20mm sample 3, in the Rally test, you can understand whether it is shoddy, cut corners.

Third, the inherent quality of the rubber plate First look at the material can be used hand and eye view, if the floor in the hands of light, insulating rubber sheet that is used tender bamboo; if the eye view of the blurred texture, indicating that the bamboo is not fresh, Is the older bamboo. Nitrile rubber has excellent resistance to fuel oil and aromatic solvents and other properties, but not resistant to ketones, esters and chlorinated hydrocarbons and other media, so oil seal products to use nitrile rubber-based.

Fourth, the concept of whether the structure of the rubber plate symmetrical balance from the rubber plate at both ends of the cross-section, whether to meet the principle of symmetrical balance, if the structure is stable.

5, to see the rubber floor of the floor layer and the glue between the layers is tight with both hands breaking, whether there will be layered. Silicone rubber has a high resistance to high and low temperature, ozone resistance and weather resistance, in the -70 ℃ ~ +260 ℃ operating temperature range to maintain its unique use of elasticity and resistance to ozone, weather and so a little, suitable for the production of thermal institutions In the required gasket, such as strong light source shade seal lining, valve pads and so on.
